Just finished installing them. Huge difference in idle quality. Little to no noise. Only drove it around the block so far. Have not noticed a loss or gain in power. Really helps stopped at a light in gear. No more shaking. Very pleased so far.

It will idle lower but the whole car shakes

Around 1000rpm

Initial is 16*

How much compression would be too much to run the Rhoads?

9 to 1 with a fresh set of stock J heads, performer rpm and an Edelbrock 650.

i have read some older posts and it seems people were happy with them. my 360 runs very well but idles pretty rough with the hughes whiplash cam. will the rhoads smooth out the idle? will there be a noticable improvement in low rpm performance. motor is in a 69 barracuda convert. 904, 7.25 with...

Do you have any info on the modification needed for the driver side?

Anyone have detailed pics and info on the modifications needed for the motor mount for a 360 going in place of a 318 in a 69 barracuda

I would love to hear how your car runs with the 302 heads. I am considering doing the same on my car. What cam are you running?

What are the chances that the original 318 in my 69 barracuda with an auto trans will have the crankshaft drilled For a pilot bearing. I have gathered almost all the parts for a 4 speed conversion and was talking to someone about doing the installation and he asked if I knew if the crank was...

I just purchased a 69 barracuda convertible with a bone stock 318 2 barrel. Will a 4 barrel carb and intake along with a set of long tube headers and dual exhaust make a significant power difference?

i just bought a 67 barracuda with a 340 in it. the heads have the letter "o" cast on the outside. i have not pulled a valve cover yet. does anyone know what this head is without a casting #.

i am trying to verify if the motor in my car is the original. 67 cuda, vin decoder says 273 4v. fender tag says it is a formula s. casting # is 2806030 273-2. thanks, adam

what is the firing order for a 273? are all small blocks the same?

it was an assembled short block from "blueprint engines". i called them and they told me it was externally balanced. i bought an external balance harmonic balancer from Napa. i saw in the summit racing catalog a flexplate for a 360 external balance, part #bmm10239. is that all i need or do i...

the engine builder told me it was externally balanced. the dampner i bought is for ext. balance. i re-used the torque converter and flexplate from the 318 so i hope that is all i need to change. thanks for all the input. adam

i just fired up my 360 stroked to 408. it started as a 1979 360 block. i bought a harmonic balancer from napa(external balance). i used the crank and water pump pulley from the original 318 that had a/c and power steering from the 69 barracuda. i started it, broke in the cam, set timing...

is an original 318 / 904 in a 69 barracuda internally or externally balanced? thanks, adam

has anyone taken all the brackets and accessories of a mid to late 90's 5.2 or 5.9 and put them on an early small block. i want to convert my 318 with a/c over to a modern compressor and serpentine belt system.

anyone used a set of eddy heads on an otherwise stock 318. i planned on just bolting on a set with a dual plane intake, 600cfm carb and headers. will i see much gain with just the stock cam? it is in a 69 cuda with an automatic.

has anyone used a set of eddy heads on a 318? results? i am considering a head swap on my 318 in a 69 cuda.

do i need different motor mounts? will all my acc. brackets and pulley's swap over to the 360? it is actually a 408 stroker from "blue print engines" i bought there short block and i will assemble it myself with edelbrock heads and a Hughes cam and lifters. anyone have any experience with "blue...
